The BDI ATB-300-6 is an 8 channel stereo analog/digital audio switcher/distribution system featuring silence detection and automatic switching. The Broadcast Devices ATB-300 is a rack-mounted solution to switching and routing in the digital or analog domain. The ATB-300 can be ordered in ten different configurations, the ATB-300-6 features eight AES I/O. The ATB-300 can be used to manually switch inputs or will automatically switch when a programmable silence interval of between 10 and 600 seconds is detected. Auto switching is programmed using a "priority list" of 4 or 8 memories depending on configuration which are programmed with input channels to search for audio in order of programmed preference. The ATB-300's intelligent search algorithm constantly monitors all inputs to allow immediate switching to the first active channel in the priority list without need to sequence through inactive channels when silence is detected.
The AES I/O module allows for up to four AES inputs and outputs per module. All I/O through this module follow the AES3 standard for interface. All I/O are 110 ohm transformer coupled. The AES I/O module allows the user to select AES output clocks including 32, 44.1 and 48 KHz sampling by DIP switch selection. Factory default is 44.1 KHz.
